| Outline of Final Research Achievements |
We found that morningness/eveningness or circadian rhythms were associated with habitual breakfast skipping in rotating-shift workers, and that this leads to unfavorable diet quality and may explain in part the differences in diet quality between rotating-shift workers and day-shift workers. In addition, shifts in sleep timing due to social factors were associated with the unfavorable diet quality which was identified in rotating-shift workers. Furthermore, it was suggested that these associations may involve executive and inhibitory functions, as well as neurotransmitters in the hippocampus and suprachiasmatic nucleus.

| Academic Significance and Societal Importance of the Research Achievements |
交代制勤務者では、夜型指向性は食の嗜好性、食事内容、睡眠の変容、抑うつレベルの増大と関連することから、夜勤への適応不全というよりも、夜勤時から日勤時への勤務（覚醒）時間帯の急激な変化にともなう内的脱同調が食事と睡眠の変容、心身の健康問題を生じうる要因である可能性がある。本研究は、その神経行動学的メカニズムの一端を明らかにした点で学術的意義がある。また、本研究の成果は、交代制勤務者の心身の健康問題の対応策の構築に対して貢献しうる点で社会的疑義がある。
